title: Regional specificity in the Drosophila midgut: setting boundaries with stem cells.
abstract: Many organs consist of distinct subregions with specialized physiological roles, but how regional boundaries are upheld during cellular renewal is largely unknown. Recently, Buchon et al. (2013) and Marianes and Spradling (2013) showed that subregions of the Drosophila midgut are maintained by patterned transcription factors and compartmentalized stem cell progeny.
